APPLICATION
Location of extraction, process of exploitation, common compounds involving the element, uses of the element and its compounds.

 

_____Although Cadmium is often compared with mercury, in terms of toxicity, it is still a valuable element in the industrial sector and nonetheless continuously exploited. As long as the demand for element #48 continues, so will it continue to be exploited and extracted from the surrounding geography.

EXPLOITATION
WHO? See "uses" below, for the type of industries which most readily need and use Cadmium.
WHAT? The exploitation of Cadmium, for industrial and chemical purposes.
WHERE? In the United States, practically all Cadmium produced, originates as a by-product of the refining of zinc ores (from Missouri, Montana, Silesia).
WHEN? Discovered in 1817; exploitation began after the industrial revolution
HOW? As most, if not all Cadmium produced in the United States, originates as a by-product of the refining of zinc ores, "Fraction Distillation" and "Electrolysis" are the two most common methods of extraction (to separate the cadmium and the zinc).
